Hello,
I have been a happy user of ESS with R for years. Recently, I've begun
to use org-mode for a lot of things, so of course I am interested in
org-babel. I checked out a version of org-mode yesterday (2-15-2010)
from git.
Using just ESS, I would write a source file, test.R, and define a
function in it, say
#identity function
test <- function(x) {
x
}
test(3)
I could then type C-c C-c (coincidentally, and happily, this is the ESS
keybinding used to send a block of code to the inferior *R* process) to
send the above lines to the running *R* process, and the output would
show up in the *R* buffer, and scroll to the bottom of the *R* buffer
since I have set
(setq comint-scroll-to-bottom-on-output t)
in my .emacs.
However, now I hope to write a file, test.org, and write something like:
* Identity function
#+begin_src R :session :results output silent
test <- function(x) {
x
}
test(3)
#+end_src
If I use C-c ' to open an R code buffer and C-c C-c, I see the same
behavior as in ESS. However, when I do C-c C-c on the code block *in the
test.org buffer*, the code is sent to the *R* buffer, but it does not
scroll. In the *R* buffer, once I do scroll to the bottom, I see the
following:
>
test <- function(x) {
x
}
test(3)
'org_babel_R_eoe'
> test <- function(x) {
+ x
+ }
> test(3)
[1] 3
> 'org_babel_R_eoe'
[1] "org_babel_R_eoe"
Can anyone
1) replicate that you don't see the scrolling, even with the
comint-scroll-to-bottom-on-output variable set to 't'?
2) suggest a way to get the *R* buffer to scroll to the bottom when I
execute a source block from an org-mode file to a running *R* session?
I am surprised by this behavior since I just assumed comint-mode should
do the right thing, so I'm not sure where the issue is! Even if this
can't be changed, I think org-babel is going to be a great use to me,
thank you!
Best Regards,
Erik Iverson
